MACHINE FOR LOCATING BUTTONHOLES IN COLLARS.

SPECIFICATION forming part of Letters Patent No. 793,008, dated June 20, 1905.

Application filed September 24, 1903. Serial No. 174,481.

To II/ZL whom it Duty cancer/2,:

Be it known that I, HENRY C. MILLER, a citizen of the United States, residing at \Vaterford, in the county of Saratoga and State of New York, have invented new and useful Improvements in Machines for Locating Buttonholes in Collars, of which the following is a specification.

This invention relates to a machine for locating central buttonholes in collars.

The object of the invention is to provide a machine for accurately forming and locating the center buttonhole exactly midway between the ends of a collar.

A further object of the invention is to provide means for quickly engaging and holding the collar ends prior to the operation of the I)uttonhole-forming mechanism.

Another object of the invention is to provide means for successively opening the endgages and moving the latter toward each other to receive a collar which is to be operated upon.

Other objects and ai'lvantages will be hereinafter referred to and be particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of a machine embodying my improvements. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged detail view of one of the gages and its operating means, the gage being in section. Fig. 4 is a plan view of the same. Fig. is a sectional view on the line 1 I, Fig. at, the gageoperating means being in full lines. Fig. 6 is an enlarged view in elevation of one of the gages. 7 tical section taken on the line 2 2, Fig. 6, illustrating a gage for positioning a collar which has no buttonhole-tabs. Fig. 8 is a detail plan view of a guide to engage the end of a collar. Fig. 2) is a detail side view of the same. Fig. 10 is a detail bottom plan view of the same. Fig. II is an enlarged detail section on the line I, 3, Fig. Fig. 12 isan enlarged detail view of the gage, partially in section, the holding means being in normal position. Fig. 13 is a similar view showing the end of a collar held by the gage. Fig. 1% is a section on the line a I, Fig. 13. Fig. 15 is a view of a modilied Fig. 7 is a verform of gage. Fig. 16 is a section showing another modilied form of gage.

A represents a bench or support, A a plate mounted on the support and extending forward of the same, as at u. The plate is provided with ways a and posts B, the latter supporting the work-table A A buttonholemachine C, mounted on a bed B, is carried by plate A and guided in the ways a.

Shafts B extend vertically through the posts B and carry at their lower ends arms ('1, which are connected by a bar K, and to the upper ends of the shafts are secured other crankarms The buttonhole-machine may be of any preferred type and comprises a head C, needlebar 0, needle 0 blade 0", cloth-clamping plates 0', and mechanism for operating the same. However, the parts described do not specifically form any part of this invention, being covered by a copeuding application filed April 19, 1902, Serial No. 103,741.

I) represents a yoke or double crank-shaft mounted in bearings D on the work-table A The shaft comprises a central horizontal portion (Z and crank-arms (Z (l, which are connected with gages E E and mechanism to operate the latter. The gages slide in ways F F in the supportA and are duplicates. Each gage is mounted on a base F, slidable in the way F, said base having formed in its upper surface a seat /1. and a projection extending through the way, which prevents its turning. An arm Ur is carried by the base, and at its outer end it is provided with a sleeve G, in which operates a movable collar-engaging pin H, pointed at its lower end /1 to engage the end Z of a collar. The upper end If of the pin is pivotally connected to one end of a lever (i by a pivot r working in a slot 7, said lever being pivotally connected by a pin to arm (I. the pin lI below the sleeve (,1", and it consists of a circular body A, formed with a central opening h", a downwardly-extemling lug or guide proper, a, and a cutaway portion 7t. A pin I-l depends from the sleeve (1 adjacent the cut-away portion W and limits the swiveling movement of the guide on the pin II.

A guide I I is loosely mounted on of which a pin F may lit.

A link I is pivoted to the outer end of the lever (5 and the lower end of said link is provided with a loop, which loosely engages the crank d, which permits an operator to raise one of the pins H without lifting the other. A spiral spring I encircles the link between a collar 1 secured thereon, and a stationary lug I which normally forces the pin H in its seat. A rod J is threaded in the base F of one of the gages E, and it is held thereto by a nut and encircling the rod is a spring J located between a movable stop J and nut J The crank-arms are formed at their inner ends with split sleeves K, clamped to the posts B, and are connected at their outer ends to the bar K, so that both gages may be operated simultaneously.

The mechanism for operating the gages is pivoted to a bracket M, depending from the support A, and consists of a bell-crank lever M, pivoted at m and carrying at its lower end a pin Z on which is pivotally mounted a second bell-crank lever L. The opposite end m of lever M is provided with a pivoted stud m, having an opening and screw n, which engages a rod N, and its opposite end is connected to a lug n on the crank J. The movement of the lever M is limited by the bracket M and a projection M and a spring M is connected to a projection M by a threaded rod 012 and nut m to normally hold the lever against said bracket, as shown in Fig. 3. To the end Zof lever L is pivoted a stud provided with a screw Z to engage a connection L, whose opposite end is pivotally connected to bar K. A link P is secured bya set-screw 32, having wings 11 to a pivoted lug P on the arm Z of lever L, and to the lower end of link P is a pedal P, mounted on a pin in standards P on the floor P. A series of socketsf are formed in the under side of each base F, into any one A roller 0 is mounted on the pin F and forks F of arms Z) straddle said roller, and a cotter-pin holds the pin in place.

In operation the operator will first press down the heel end of pedal P, which will actuate the rod L and connecting-rod K in the direction of arrow 1 in Fig. 3, and through the connections move the gages toward each other, the gages being limited in their movement by the stop J. A continued pressure on the treadle when the stop J contacts with the frame will overcome the resistance of drawn toward each other and the pins H lifted, the operator will now place the edges of the tabs of the collar against the guides (see Figs. 7 and 14:) and then releasing pressure on the pedal and spring M draws lever M to its normal position, and through the connections N releases the links I, the springs I forcing the pins H down, and the ends of the collar are pressed into the seats it. The operator now transfers pressure to the toe of the pedal, pulling rod P, which actuates lever L and moves the bar K, which will simultaneously spread the gages an equidistanee from the buttonhole-sewing machine, the length of the collar stopping the movement of the gages. Clamping-plate 0*, previously raised, is now closed on the collar and holds it while the buttonhole is formed.

By virtue of the guides being swiveled on the pins H it is not necessary for the operator to carefully level the collar when positioning the ends of the same. The distance between the gages when moved toward each other preparatory to receiving a collar is less than the length of the collar, so that when the operator introduces the ends of the latter under the pins H and against the guides the edges may be slightly angularly disposed. WVhen the gages are spread apart and the collar is drawn taut, the edges bearing against the guides cause the latter to turn to permit of the collar being flattened without ruffiing the fabric, which insures the sewing mechanism forming the center buttonhole in the exact predetermined place.

The gages accurately locate the collar with reference to the buttonhole-machine so that when the center buttonhole is formed it will be exactly in the center of the collar, as will be readily understood.

In Fig. 15 I have illustrated a modified form of gage H which is substantially the reverse of the preferred form. The pin I-I is fixed and the ooacting element H having a seat, is movable and is operated by an arm H connected to link I by a set-screw it manipulated in the same manner as hereinbefore described.

In Fig. 16 a fixed pointed lower engaging element it" is located under a movable pin H, which has a seat, the guide coacting with both forms of gages, as shown in Figs. 15 and 16.
